Section 1 / Using Structs

This topic has already been covered indirectly by examples provided in:

alignment
and defining

To summarize using structs:

All structs have a base address
The base address corresponds to the beginning of the first data member
All subsequent data members are offsets relative to the first
In order to use a struct correctly, you must have first calculated the offsets of each data member
Sometimes there will be padding between data members due to the need to align all data members on natural boundaries.
